Super Lovers
In my opinion this is Komatta 2.0 - The characters in this manga are much more forward in their feelings for each other. Though it does take a while for them to outwardly become 'mature' about it, as the difference in their age is quite big, there is definitely a physical element involved with them and they speak about it to each other as well.
Love Stage!!
Pure lovey-dovey angst, smut and yaoi goodness. The uke is extremely feminine in looks and mannerisms, so if it's not your thing then probably best to avoid it. Otherwise... Enjoy! ^^
Also, I love the artwork of this manga. It has a very 'pretty' and shoujo feeling to it but it's just so smooth and perfect that I can forgive it. <3
Hidoku Shinaide
Also one of my favourites. If you can get past how questionable the main pairing's first encounter is and how they fall for each other, then this is a really good read! Great artwork as always by this mangaka and a solid story to go with it. <3
Also~~ Lots of really hot, splendidly drawn smex ~~ ^_^ ~~
Elektel Delusion
This is probably my all-time favourite manga. One, because of the amazing artwork (as always) by Nekota Yonezou and Two, because the story and the characters are so damn cute. I'm always looking forward to more updates from this manga. If you want lots of very sexy, very attractive male/male smut with believable and interesting characters, lots of humour and with the occasional wacky plot twist this manga is Definitely for you. <3
Otouto ja Irarenai!!
I really like this manga. One of two I've read so far that involve two brothers falling in love (step-brothers). I think that the way it's written is very well done and believable and the artwork is very easy on the eyes. I found myself really egging them on and getting frustrated when they couldn't voice their feelings early on.
I love the pairings in this manga and I'm looking forward to the updates ^^ GANBATTE! <3
Datte Maou-sama Wa Kare Ga Kirai
This one is certainly different. It follows the same sort of principle of any 'possessive lover' manga but the protagonists are both some kind of modern-day answer to 'hero' and 'devil king' hence the title I suppose. It is the 'hero's' objective to conquer the 'devil king' and vice versa but the devil king is a caring 'good guy' who doesn't want to do bad things and does his best not to do so and the 'hero' is a 'bad' guy who only wants to dominate and 'win' over the 'devil king'. It's an interesting read, though I wouldn't say it's for everyone. However, I think it's at least worth trying. It definitely has promise. ^^
